MULCAHY BY fiwz fl/M i ATTORNEY.

Patented Sept. 29, 1936 UNITED STATES PATENT OFFICE WINDOW POLE James E. Mulcahy, Cleveland, Ohio Application September 2 Claims.

This invention is directed to improvements in window poles and has for its general object the provision of a Window pole so arranged that it cannot mar or otherwise damage the edges of a window sash by hooking the end of the pole onto it In the past, window poles have been so constructed that the user could engage edges of the window sash by hooking the end of the pole onto the sash cross members, thus marring and often destroying the window sash, causing the replacement of the entire sash. While the window poles are not intended for use in this manner, nevertheless it has become a customary practice, due to the fact that it is the most convenient way to use the pole.

The present invention provides a window pole, no part of which will project in any direction sufficiently to provide a shoulder by means of which either a muntin separating the window panes or the frame itself may be engaged by the operator for effecting the downward movement to be imparted to the Window, thereby eliminating both the marring and breaking of the sash parts and eliminating to a great extent the danger of breaking a window pane.

Further objects of the present invention will become more apparent from the specification, reference being had to the accompanying drawing in which I illustrate a preferred form of the invention. The essential and novel characteristics of the invention will be summarized in the claims.

In the drawing, Fig. 1 is an enlarged fragmentary side elevation of the window pole, certain parts being broken away to more clearly illustrate the internal construction thereof; Fig. 2 is an inside front view of a window, with which the pole is arranged to be used; Fig. 3 is a section through the window sash taken substantially along the line 33 of Fig. 2, illustrating the pole in proper position to lower the sash; Fig. 4 is a fragmentary vertical section, as indicated by the line 4-4 on Fig. 3; Fig. 5 is a substantially horizontal section, the plane of the section being illustrated by the line 5-5 on Fig. 3; Fig. 6 is a section through the pole tip, as indicated by the line 6-6 on Fig. 1.

My invention contemplates the provision of equipment for a window which will facilitate the safe and convenient opening of the upper sash and the closing of the lower sash. It includes a window pole, equipped with a special tip, arranged in such a manner that it will interlock with cooperating socket plates in the window 26, 1935, Serial No. 42,334

sash frame, to prevent slipping of the pole, and consequent breaking of a window pane or marring of the sash structure. The pole tip is likewise so arranged that the operator may not use the pole in connection with projecting sash parts instead of with the cooperating socket plates.

In the drawing, I have indicated, in Fig. 2, a window comprising upper and lower sash members IE1 and II, each provided with a socket IS in its upper region, which is covered with a socket plate l2, secured to respective upper sash members l6 and I! by suitable screws 2|, and arranged to receive the pole tip. As shown, each window sash comprises a series of panes separated by vertically extending mullions l4, and horizontally extending muntins IS.

The socket plates |2 are provided with specially formed apertures, comprising as shown in Fig. 4, an upper part l9 sufiiciently large to permit entrance of the enlarged end 36 of an arm 3| formed on a metallic tip member 32, which is secured to the upper end of an operating pole or rod 33. The lower part of the aperture is in the form of a slot, whereby the arm 3| may fit thereinto, thus causing the enlargement 36 of the arm to be interlocked with the socket plate in the manner shown in Figs. 3 and 4.

In my window pole, which is illustrated in Figs. 1 and 3, the underside of the arm 3| is a curved surface 34 and inclines upwardly, such inclined portion extending across the head 30, as the result of which the arm cannot be hooked onto any part of the window sash, as is the case with the customary pole, but can only be inserted into the socket of the plate I2, which is designed for its use. Thus, the user cannot mar the edges of a window sash, by hooking the ends of the pole onto it. With prior poles, the edges of the sash have been repeatedly so marred that it has become necessary to replace the sash, and such improper use is an impossible accomplishment with a pole made in accordance with my invention.

With some window poles made in the past, it has been possible to rotate the poles degrees. bringing the side edges of enlarged heads into cooperation with the muntin members l5 of the sash. In my improved pole, as shown in Figs. 5 and 6, side walls of the arm 3| which join the enlarged head 30 to the pole tip comprise curvilinear surfaces 35. Such surfaces prevent the gripping of any sash surface by the pole tip, regardless of whether or not the pole is swung about its axis. The intersection of the curvilinear surfaces 35 with the under curvilinear surface 34 is such that were the user to contact a frame part with the head 30 of the pole when the pole is swung about its axis, a camming surface will be presented to the pole tip and gripping of the sash part would be prevented. To further insure that the side edge sides of the enlarged portion 30 cannot be used to engage the sash, I retain the width of such enlarged head slightly smaller than the diameter of the pole tip at the junction of the arm 3! therewith.

The upper end of the tip is provided with a socket 36 which is substantially in alignment with the axis of the pole. A suitable mushroomshaped tip 31 made from a yieldable substance, such as rubber, is positioned within this socket with the head thereof engaging the top of the pole as shown in Fig. 1.

From the foregoing description it will be seen that I have provided a pole structure in which the pole cannot be hooked onto any part of the window frame, thereby preventing the damage to the frame by such poles and eliminating the necessity of replacing the sash because of such usage.

I claim:

1. A window pole having a socket in the upper edge thereof, the axis of the socket being substantially in alignment with the axis of the pole. a mushroom-shaped yieldable tip positioned within the socket and having the head thereof engaging the top of the pole, said pole having an arm extending laterally therefrom and terminating in a rounded head portion, no part of which projects in any direction from the arm sufficient- 1y far to provide a shoulder, by means of which a sash muntin may be engaged for pulling down a window sash.

2. A window pole having a single arm extending laterally from one end thereof and being adapted for raising and lowering a window, the arm terminating in a rounded head, no part of the head or arm being projected in any direction from the pole sufiiciently far to provide a shoulder by means of which any part of a window sash may be engaged for pulling down the sash, said pole being adapted for use only with a preformed socket into which the head is adapted to be extended for the purpose of moving the sash.
